** Scotland's leopard **
A paw print left by a rumoured 'big cat' in Scotland does belong to an exotic cat, says Fife Police.
A cast of the print, made by a wildlife crime officer in October 2005 near Glenrothes, is not good enough to confirm a species, although a black leopard is most likely.
The so-called Beast of Balbirnie is not full-grown and thought to be an offspring of a leopard released illegally in the 1990s.
